During percutaneous coronary intervention, guidewire fractures are very exceptionally encountered in medical practice, but can cause fatal complications such as intracoronary thrombus formation, embolization and perforation. Removal of the remnant segments of guidewire is important for the prognosis. There are several methods being recommended for the treatment of fractured guidewire remnants. However, the best treatment of remnant guidewire filament is still unclear. Herein, we present a case where we did not completely remove remnant guidewire filaments that caused fatal coronary thrombosis.

Multi-vessel coronary artery disease (MVD) frequently features ambiguous or intermediate lesions that may be both serial and complex, suggesting that multiple regions require revascularization. Percutaneous coronary intervention (PCI) is associated with various challenges such as appropriate identification of lesions that should be treated, the choice of an optimum revascularization method, and limitations of long-term outcomes. Optimal patient selection and careful targeting of lesions are key when planning treatment. Physiology-guided decision-making (based on the fractional flow reserve) can overcome the current limitations of PCI used to treat MVD regardless of clinical presentation or disease subtype, as confirmed in recent clinical trials. Here, we review the use of physiology-guided PCI for patients with MVD, and their early and late outcomes.

PURPOSE: The aim of this study was to evaluate and compare the long-term clinical outcomes of the spot drug-eluting stent (DES) implantation strategy, which is used to minimize implanted stent length and the number of stents, versus full lesion coverage for treatment of coronary artery stenoses. MATERIALS AND METHODS: We evaluated 1-year clinical outcomes of 1619 patients with stent implantation for a single coronary lesion. They were divided into two groups: those treated by full lesion coverage (n=1200) and those treated with the spot stenting strategy (n=419). The combined occurrence of 1-year target vessel failure (TVF), including cardiac death, target-vessel related myocardial infarction, or ischemia-driven target-vessel revascularization was evaluated. RESULTS: The spot DES implantation group had a shorter stent length (23.14+/-9.70 mm vs. 25.44+/-13.24 mm, respectively; p<0.001) and a fewer number of stents (1.09+/-0.30 vs. 1.16+/-0.41, respectively; p<0.001), even though the average lesion length was similar to the full lesion coverage group (21.36+/-10.30 mm vs. 20.58+/-10.97 mm, respectively; p=0.206). Spot DES implantation was superior to full DES coverage with respect to 1-year TVF (1.4% vs. 3.3%, p=0.044). Cox proportional hazard model analysis showed that the risk for 1-year TVF was almost 60% lower among patients who received spot DESs compared to those who received full DES coverage after adjustment for other risk factors (HR=0.40, 95% confidence interval=0.17-0.98; p=0.046). CONCLUSION: Minimizing stent length and the number of stents with overlapping by spot DES implantation may result in reduced rates of 1-year TVF, compared with full DES coverage.

The study aimed to examine the effects of virtual reality (VR) technology-based phase I cardiac rehabilitation (CR) program in elderly coronary heart disease (CHD) patients after percutaneous coronary intervention (PCI). Thirty-six cases of elderly CHD patients who underwent PCI in the First Affiliated Hospital of Chongqing Medical University from June 2022 to April 2023 were recruited by convenience sampling method. The patients were randomly assigned by means of random digital table method to two study groups: control group (n = 18), which received conventional nursing intervention after PCI, and experimental group (n = 18), which received a combined program of conventional nursing intervention together with CR program based on VR technology. The 6 min walk test (6MWT), Simple Physical Performance Battery (SPPB), SF-36 scale, Hospital Anxiety and Depression Scale (HADS) and Impact of Events Scale-Revised (IES-R) were tested before and after rehabilitation. Moreover, the incidence of major adverse cardiovascular events (MACE) was recorded at 3 months after PCI. After VR-based CR, the 6MWT distance and SPPB scores of patients in the experimental group were higher than those in control group (P < 0.05). The HADS scores and IES-R scores of the patients in the experimental group were lower than those in control group (P < 0.01), and the difference in SF-36 scale scores was not statistically significant between two groups (P > 0.05). The incidence of MACE was not significantly different at 3 months after PCI (P > 0.05). These results suggest that VR-based phase I CR program mitigates the degree of PCI postoperative stress, anxiety, and depression in elderly CHD patients, however, enhances the resistance to fatigue and does not increase the risk of adverse cardiac events, suggesting it is a safe intervention.

Complex coronary heart disease (CHD) has become a hot spot in medicine due to its complex coronary anatomy, variable clinical factors, difficult hemodynamic reconstruction, and limited effect of conservative drug treatment. Identifying complex CHD and selecting optimal treatment methods have become more scientific as revascularization technology has improved, and coronary risk stratification scores have been introduced. SYNTAX and its derivative scores are decision-making tools that quantitatively describe the characteristics of coronary lesions in patients based on their complexity and severity. The SYNTAX and its derivative scores could assist clinicians in rationalizing the selection of hemodynamic reconstruction treatment strategies, and have demon-strated outstanding value in evaluating the prognosis of patients with complex CHD undergoing revascularization treatment. The authors in this article summary the practical application of SYNTAX and its derivative scores in complex CHD in order to deepen the understanding of the relationship between the choice of different revascularization strategies and SYNTAX and its derived scores in complex CHD and provide a further reference for clinical treatment of complex CHD.

Acute coronary syndrome (ACS) is one of the leading causes of death in cardiovascular disease. Percutaneous coronary intervention (PCI) is an important method for the treatment of coronary heart disease (CHD), and it has greatly reduced the mortality of ACS patients since its application. However, a series of new problems may occur after PCI, such as in-stent restenosis, no-reflow phenomenon, in-stent neoatherosclerosis, late stent thrombosis, myocardial ischemia-reperfusion injury, and malignant ventricular arrhythmias, which result in the occurrence of major adverse cardiac events (MACE) that seriously reduce the postoperative benefit for patients. The inflammatory response is a key mechanism of MACE after PCI. Therefore, examining effective anti-inflammatory therapies after PCI in patients with ACS is a current research focus to reduce the incidence of MACE. The pharmacological mechanism and clinical efficacy of routine Western medicine treatment for the anti-inflammatory treatment of CHD have been verified. Many Chinese medicine (CM) preparations have been widely used in the treatment of CHD. Basic and clinical studies showed that effectiveness of the combination of CM and Western medicine treatments in reducing incidence of MACE after PCI was better than Western medicine treatment alone. The current paper reviewed the potential mechanism of the inflammatory response and occurrence of MACE after PCI in patients with ACS and the research progress of combined Chinese and Western medicine treatments in reducing incidence of MACE. The results provide a theoretical basis for further research and clinical treatment.
